I love this but am pretty hopeless at games. I'm on the 5th world, so don't give up Lyndsey, you'll get there!
The co-operative play mode is great, I'd have never made it past some bits if my infinitely more talented (and patient) mate hadn't come round to be Luigi.
I think I must have been waiting for this game since Super Mario 3 pretty much, I never had a Snes or DS so didn't get any of those ones, and though I liked Yoshi's story on N64 (or was it Gamecube) this is the closest to the classic Mario action.
